Abstract: PURPOSE:To eliminate the need for labor of forming a program, by providing a fine dividing circuit, end point erase circuit, and route erase circuit, and making the recognition of the logical circuit and the like with an elelctronic computer itself. CONSTITUTION:In a finely dividing circuit 10, an original video signal is finely divided into small matrixes, the pattern of the small matrixes is compared with a reference pattern, ''1'' is converted into ''0'', and ''0'' into ''1'' for the correction of pattern. An end point erase circuit 20, if one end of the linking state of ''1'' of the small matrix constitutes a branch not connected elsewhere, converts ''1'' into ''0'' for the elimination of release of the branch by leaving another end of the branch. This output is given to a route erase circuit 30 to detect the presence of the branch point from the linking state of ''1'' in the small matrix. The branch from the branched point to another end point is changed into ''0'' for release and rejection. Thus, the pickup of symbol is made with the output of the circuit 30.

Filed: 1988-07-27
Abstract: PURPOSE:To enhance convergence of air-fuel ratio control by integrating correction factor decided according to a deviation between the target air-fuel ratio nd the actual air-fuel ratio and correcting the basic fuel injection quantity according to the integrated value. CONSTITUTION:In a control circuit 24, when an air-fuel ratio sensor 22 is active, the target air-fuel ratio is calculated according to the engine rotating speed, intake air quantity and water temperature. Secondly, the actual air-fuel ratio corresponding to output of the air-fuel ratio sensor 22 is read in a digital value. Correction amount K2 is obtained as a function of proportion term, integrating term and differentiating term from a deviation between the actual air-fuel ratio and the target air-fuel ratio and the air-fuel ratio change speed. Further, correction amount K3 forming a map by the intake air quantity, the engine rotating speed and water temperature is increased and decreased corresponding to the correction amount K2. Finally, the basic fuel injection time is corrected using these correction amounts K2, K3. Thus, when the target air-fuel ratio and the actual air-fuel ratio is large and the correction amount K2 becomes larger, the correction amount K3 is quickly converged according to the amount.
